Synthesis, Properties and Reactivity Studies of a Hetero‐dicopper Complex Consisting of a Porphyrin and a Bispyridylamine Moiety Connected by a Xanthene Backbone

Synthesis, characterization and reactivity studies of a hetero-dicopper complex, particularly towards oxygen reduction are presented. A bischlorido copper(II) trishistidine-type coordination unit is positioned directly above copper porphyrin unit. The close distance between the two fragments secured by rigid xanthene backbone. Surprisingly, dinuclear complex not active unlike earlier published mononuclear analogues with bispyridylamine center. However, compound architecture this multinuclear metal interesting can play an important role in development new catalysts for ORR.
